Merge tag 'usb-6.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB fixes from Greg KH:
 "A few small USB fixes for 6.1-rc3. Include in here are:

   - MAINTAINERS update, including a big one for the USB gadget
     subsystem. Many thanks to Felipe for all of the years of hard work
     he has done on this codebase, it was greatly appreciated.

   - dwc3 driver fixes for reported problems.

   - xhci driver fixes for reported problems.

   - typec driver fixes for minor issues

   - uvc gadget driver change, and then revert as it wasn't relevant for
     6.1-final, as it is a new feature and people are still reviewing
     and modifying it.

  All of these have been in the linux-next tree with no reported issues"
